  1. Could we use Nitrous Oxide on propeller plane's engine for a speed boost (aka improvised afterburner for propellers)? Even if the engine itself is already on WEP (War Emergency Power)?

    Bad science in fiction Hall of Shame

    Hydrogen has 3 isotopes 1H (Hydrogen), 2H (Deuterium) and 3H (Tritium) and they are all present in hydrogen. So if Hydrogen is ‘depleted’ and 2H and 3H isotopes are removed, the part that is mostly a mix of 2H and 3H could be referred to as ‘enriched Hydrogen’. If this ‘enriched Hydrogen’ (2H and 3H) was further process and the 3H was removed; the 3H could be referred to as ‘super enriched Hydrogen’. While the bulk of the remainder which is mostly 2H could now be referred to as being depleted Hydrogen – but we already have ‘depleted Hydrogen’ (the first process where 2H and 3H was removed) so it is specifically referred to as ‘depleted 2H’. This would be 2H with very little tritium in it (if any). This makes ‘depleted 2H’ a very specific name for specific product. Depleted Deuterium can only happen because Hydrogen has three isotopes of interest, and so there is two steps instead of one. There would be no Depleted Tritium as there is nothing else to take out I've forget where I saw this term, it's already a very long time ago, but the only thing that I remember it's use is on "mass reactive depleted deuterium shells". Perhaps they were looking for a "cool" sounding isotope/element to correspond with depleted uranium (very dense non-radioactive, mostly, substance) and blew it. Correct me if I'm wrong
  4. The fact that Bismarck's rudder jammed probably accounts for the condition of the ship the moment the torpedo hit. It was maneuvering at battle speed, where, aside from rudder being turned, the ship's propeller spins at high RPM. An exploding torpedo on ship's stern could deform the structural parts of the ship which could jam the rudder or destroy the propeller (also happened with HMS Prince of Wales, which is sunk after just a single torpedo hit). There are reports that the personnel on board tried to destroy the rudder connection to prevent Bismarck being steering locked, with the propellers being used for turning (which is very difficult, considering Bismarck has triple propeller layout instead of quad, making it very limited in terms of being used as a substitute rudder)

    dihydrogen monoxide is basically H2O (water), but despite scientific-sounding-name, it still isn't cool enough for sci-fi weapon ammo Oh, another example about bad science, from Iron Man 2: 1. Tony's arc reactor is slowly killing him through "palladium poisoning". Ignoring the question of how the palladium fuel is seeping out of his arc reactor in the first place (implying a containment breach), palladium isn't really all that harmful to humans. (Except on excessive quantities) 2. Nick Fury tells Tony Stark that Tony's been injected with "Lithium Dioxide" in order to remove the effects of palladium poisoning. This implies that lithium has at least four electrons to give up, while it actually only has three. And taking two of them requires more than just some oxygen. Apparently the movie confuses the type of chemical bonds in a molecule. The wrong part is the name - it should be: lithium superoxide. And it indeed does exist (at very low temperatures, but still...). Then there's the fact that injecting someone with as powerful an oxidising agent as superoxide would, in real life, have some pretty spectacularly nasty and possibly fatal effects. 3. During Justin Hammer's overly boasting description of the Ex-Wife bunker buster missile, he only gives one notable piece of technical information about it. He describes the missile as containing a "cyclotrimethylenetrinitramine RDX burst". Two different terms for the same explosive substance back-to-back (cyclotrimethylenetrinitramine IS the RDX) 4. Let's not started on him jury-rigging a freakin' Hadron Collider in his garage to "create a new element"

    The frequent use of "Depleted Deuterium" in a lot of sci-fi weapons (as a cooler-sounding version of depleted uranium ammo) is particularly bad science in itself due to the fact that you can't even get depleted Deuterium, because it's a stable isotope
  7. But what about steering gear? If the bridge gets destroyed, then there's no control of rudders right?
  8. On 1-1 battleship duel, if one battleship (with sheer luck) managed to land a main gun shell on another's bridge, causing it to explode and completely destroying the bridge, does it becomes an ship equivalent of "headshot"? Does it disables the ship, heavily crippling it or not a big deal at all and still combat capable? Especially since the bridge is the command center of the entire ship
  9. Ah, the KS-23, the shotgun with the largest caliber, with multiple shell types, which consists of "Shrapnel" buckshot rounds with a 10- or 25-meter range, "Barricade" slugs to destroy the engine block of a car at 100 meters, "Volna" and "Strela" training or less-lethal rounds, and "Bird cherry" and "Lilac" tear-gas grenades, which use a rifle grenade adaptor Though to be fair, when we are talking about caliber for shotguns, it's rather different story compared to other firearms, mainly despite it's large caliber, shotgun shells usually have low chamber pressure, so even with a caliber of 23 mm, shotgun shell is generally useless when firing at aircraft when compared with other 20 mm caliber guns (Above the Heavy machineguns, the classification goes to Autocannon, which has caliber ranging from 20-60mm) So yeah, like what @DDE said, it mucked things up

    ARS sisters here, it does indeed Let's see... How about @JadeOfMaar?

    What did you do in KSP today?

    I made something... Not because I'm running out of idea, but this simple drone is a part of something... bigger
  12. Does Focke-Wulf Triebflugel design considered airworthy? If it's plausible for such design to be considered airworthy, how's the performance when compared with conventional aircraft design? Especially on it's intended role as interceptor aircraft The three rotor blades were mounted on a ring assembly supported by bearings, allowing free rotation around the fuselage. At the end of each was a ramjet. To start the rotors spinning, simple rockets would have been used. As the speed increased, the flow of air would have been sufficient for the ramjets to work and the rockets would expire. The pitch of the blades could be varied with the effect of changing the speed and the lift produced

    Nothing much to do today, just doing some BDA dogfight test
  14. Many thanks! Someone gave me that pics of aircrafts and I'm as interested as him to know what's the name of these. I'm looking forward for this series, looks interesting!
